Function Features

• Independent Isolation Design Enhances Anti-Interference Performance

  Each of the 8 input channels adopts an independent isolation design, which is isolated from each other as well as from the module logic and the ground. This design completely eliminates signal crosstalk between channels, and can effectively prevent the module from being damaged by external voltage surges or electromagnetic interference. It ensures the purity and stability of input signals in complex industrial electromagnetic environments.

• Dual Compatibility and Bidirectional HART Communication

  It supports mixed connection of standard 4 – 20mA analog devices and HART intelligent devices without modifying hardware or adjusting circuit connections. Each channel is equipped with a dedicated FSK modem to realize bidirectional digital communication with HART devices. The DCS can not only collect analog process data but also retrieve device fault diagnosis information and send configuration commands to adjust device parameters through the module.

• Long-Distance Transmission and Stable Power Supply Guarantee

  It supports a maximum cable length of 3030 meters when connecting with field devices, which fully meets the wiring needs of large-scale industrial sites such as large chemical plants and power plants. The independent current-limited loop power supply for each channel ensures stable power supply for field HART devices, avoiding power supply abnormalities caused by shared power supply and improving the reliability of the entire system.

• Convenient Installation and Strong Environmental Adaptability

  It supports DIN rail mounting, which simplifies the installation process and is easy to arrange and combine with other modules in the control cabinet. With an IP67 protection rating and an operating temperature range of -40°C to +70°C, it can resist the erosion of dust, moisture and even some chemical substances, and can operate stably in harsh working conditions such as outdoor control stations and high-corrosion chemical workshops.

Application Scenarios

• Petrochemical Industry

  It is widely used in oil refineries, chemical plants and oil and gas transmission stations. It is connected with HART-compatible pressure transmitters, flow meters and temperature sensors on reactors, distillation towers and long-distance pipelines. It collects parameters such as reaction temperature, medium flow rate and pipeline pressure in real time, and feeds back equipment operation status to the DCS. The control system adjusts process parameters in time according to the data to avoid safety accidents such as material leakage and over-temperature reaction.

• Power Industry

  It is deployed in coal-fired, gas-fired and nuclear power plants, matching with HART temperature sensors on boilers, pressure transmitters on steam turbines and liquid level sensors in water supply systems. It monitors key parameters such as boiler combustion temperature, steam pressure and circulating water level in real time. It helps operators find abnormal equipment conditions early and adjust operation strategies, ensuring continuous and stable power generation of the power plant and preventing equipment damage caused by parameter deviation.

• Water and Wastewater Treatment Industry

  It is installed in urban sewage treatment plants and industrial wastewater treatment workshops, connected with HART water quality sensors, flow meters and liquid level transmitters. It collects data such as pollutant concentration, treatment water flow rate and sedimentation tank liquid level. The control system adjusts the dosage of coagulants and disinfectants and the operation speed of water pumps according to the data to ensure that the treated water meets the discharge standards and improves the efficiency of water treatment.

• Building Automation System

  It is integrated into the automation control systems of large commercial buildings, high-end office buildings and shopping malls, connected with HART air quality sensors, temperature and humidity transmitters and water supply pressure sensors. It monitors indoor temperature and humidity, air pollutant content and water supply pipeline pressure in real time. It cooperates with air conditioning, ventilation and water supply systems to realize automatic adjustment of the internal environment of the building, improve the comfort of the building and achieve the purpose of energy saving.

• Automated Manufacturing Industry

  It is applied to automated production lines such as automobile assembly, electronic component processing and packaging. It is connected with HART pressure sensors on assembly robots and temperature sensors on molding equipment. It collects signals such as the pressure of robot clamping parts and the temperature of molding dies. It ensures that the equipment operates according to the set parameters, triggers an alarm immediately when an abnormality occurs, reduces the scrap rate of products, and improves the stability and production efficiency of the production line.
